Earth sensing[edit]

Advanced Baseline Imager (ABI) for imaging Earth’s weather, climate and environment.[edit]

Built by Harris [1] for the GOES - R line of Satellites. The imaging capabilities of the ABI is superior to previous imagers in several ways:

Spectral resolution:[edit]

This instrument has 16 bands (Over the last GOES Imager, which only had 5 bands[2]):

2 Visible Bands:

  • Band 1: 0.45 - 0.49 μm ("Blue")
  • Band 2: 0.60 - 0.68 μm ("Red")

4 Near IR Bands:

  • Band 3: 0.847 - 0.882 μm
  • Band 4: 1.366 - 1.380 μm
  • Band 5: 1.59 - 1.63 μm
  • Band 6: 2.22 - 2.27 μm

10 other Infrared Bands:

  • Band 7: 3.80 - 3.99 μm
  • Band 8: 5.79 - 6.59 μm
  • Band 9: 6.72 - 7.14 μm
  • Band 10: 7.24 - 7.43 μm
  • Band 11: 8.23 - 8.66 μm
  • Band 12: 9.42 - 9.80 μm
  • Band 13: 10.18 - 10.48 μm
  • Band 14: 10.82 - 11.60 μm
  • Band 15: 11.83 - 12.75 μm
  • Band 16: 12.99 - 13.56 μm
Temporal resolution:[edit]

This changes depending on the type of image.

  • Imaging of entire western hemisphere occurs every 5 to 15 minutes, while previously this was a scheduled event, with at most three photos per hour. [3]
  • Imaging of the continental United States once every 5 minutes, compared to one every 15 minutes in previous satellites
  • One detailed image over some 1000 by 1000 km box every thirty seconds, a capability previous imagers did not have
Spatial resolution:[edit]

Spatial resoltuion depends on what band is being used. Band 2 has a spatial resolution of 500 meters Bands 1,3,4,5 and 6 have spatial resolutions of 1 km All other bands have spatial resolutions of 2 km


Geostationary Lightning Mapper (GLM)[edit]

This instrument is used for measuring lightning (in-cloud and cloud-to-ground) activity. To do this, it considers a single channel in the NIR (777.4 nm) constantly, even during the day, to catch flashes from lightning.

The sensor has a 1372 by 1300 pixel CCD, with an 8-14 km spatial resolution (with the resolution decreasing near the edges of the FOV). The GLM has a frame rate of 2 milliseconds, meaning it considers the entire study area 500 times every second.[4].
